What Is the LifeVest Wearable Defibrillator?

The LifeVest wearable defibrillator is a treatment option for sudden cardiac arrest that offers patients advanced protection and monitoring as well as improved quality of life.

The LifeVest is the first wearable defibrillator. Unlike an implantable cardioverter defibrillator (ICD), the LifeVest is worn outside the body rather than implanted in the chest. This device continuously monitors the patient's heart with dry, non-adhesive sensing electrodes to detect life-threatening abnormal heart rhythms. If a life-threatening rhythm is detected, the device alerts the patient prior to delivering a treatment shock, and thus allows a conscious patient to delay the treatment shock. If the patient becomes unconscious, the device releases a Blue™ gel over the therapy electrodes and delivers an electrical shock to restore normal rhythm.

Comfortable, lightweight garment is washable and can be worn all day, except when bathing and showering.

This monitor is worn in a holster around the waist and collects ECG data from the sensing electrodes which can later be sent to a doctor via modem.

If a life-threatening arrhythmia is detected, this alarm module alerts the patient with audible, visual and tactile alarms. A conscious patient can prevent a shock by simultaneously pressing two response buttons.

In the event of a life-threatening arrhythmia, these dry therapeutic electrodes will automatically deploy conductive gel prior to delivering a shock.
